Important Notes
Hearing is very important to you and to us so please take care when operating this equipment.
It is strongly recommended that you follow the listed guidelines in order to prevent possible
damage or loss of hearing.
ESTABLISH A SAFE SOUND LEVEL
• Over time your hearing will adapt to continuous loud sounds and will give the impression that
the volume has in fact been reduced. What seems normal to you may in fact that be harmful.
To guard against this BEFORE YOUR HEARING ADAPTS set the volume at a low level.
• Slowly increase the level until you can hear comfortable and clearly and without distortion
• Damage to your hearing is accumulative and is irreversible.
• Any ringing or discomfort in the ears indicates that the volume is maybe too loud.
Once your have established a comfortable listening level, DO NOT INCREASE THE SOUND
LEVEL FURTHER.

set the volume level.
